Q&A - P3 Science

Extracted this question from CHIJ CA1 question 18. There is a picture of a plant that requires students to identify the parts.


The answer state singular term like flower, root, leaf and stem. Would it still be acceptable to name the parts in plural term as flowers, roots and leaves?
Thanks.

Hi,


Appreciate someone can help on the following question:

Which plant W,X,Y,Z will be alive after 2 weeks?

Plant W has air, water n sunlight ( no nutrients)
Plant X has air, sunlight n nutrients (no water)
Plant Y has air, water n nutrients (no sunlight)
Plant Z has air (no water, sunlight n nutrients)

Ans (1) W only
(2) X and Y only
(3) W and X only
(4) none of the above

Should the answer be 1 or 4? Answer given is 1.

In the Ultimate Science guide, it states ‘Plants need water, air, sunlight and nutrients to grow’. So not sure do I need to take nutrients into consideration as I understand that basic need of plants are air, water n sunlight.

Also some books will just states plants like all living things need air, water and food to survive. So if in open-ended question like ‘what do plants need to survive.’ What should be the appropriate answer?

Thank you.

Hi mum2BG

Could it be because the question is only asking if the plants will be "alive" (=survive) after 2 weeks? If the question is asking if the plants will "grow", nutrients shd b included?
Just my wild guess… Also struggling to comprehend the correct techniques of answering Science questions…
Maybe other parents can share their thoughts?

Look into your kid work book or worksheets to see what the teacher marked for this kind of questions. If I am not wrong, plants only need air, sunlight to make food and water to survive.

I have checked my four guides. Two state air, sunligtw and water to survive, the other two state addition of minerals/nutritions to grow. You can double check with your science teacher to clarify. My kid said nutrition is for healthygrowth, without, should still able to survive for two weeks.

Living things need air,food,water.Plant make food using sunlight.So I go with answer(1)

This is a very simple question. The answer is 1. Plant W.
Why? Because without water, plants cannot survive. So Plant X and Plant Z cannot be the answer. Without food, plants cannot make food and will not survive. So plant Y cannot be the answer too. After eliminating the rest, that concludes that Plant W is the only answer. All plants need water, air and sunlight to survive. Without nutrients such as fertiliser, plants can still survive.
Hope I have explained to you clearly to clear your doubt.

Anyone can help with this P3 question?


A desert is a hot and dry place. However there are animals and plants that can stay alive in the desert. State a reason why they can survive in such conditions.

Hi,


May I know do all fruits contain seeds? Thank you.

Answer: No
Why? Not all fruits have seeds. There are seedless fruits around. Eg: seedless grapes, seedless watermelons etc

Banana is a herbaceous flowering plant.
Banana plant is not a tree.
Banana does not have seeds
Banana plant reproduce by suckers.

My DD's teacher corrected the OE Question last year and the exact answer given was need plants water, air, sunlight and nutrients to stay alive.
